Musflex pill is a muscle relaxant formulated with 350 mg of Carisoprodol as an active compound. It is manufactured in Honduras by MC Pharmaceutical Company and helps manage short-term acute pain within 30 minutes of intake.  



Have you come across the word "Musflex pill" yet? If not, we have you covered. 

Suffering from body pain has been associated with reduced quality of life and a significant increase in medical expenses for the longest time. According to CDC, approximately 8% of adults suffer from chronic pain in the USA, making analgesics a booming sector in the pharmaceutical industry [1].

Soma pills and Musflex are two effective analgesics that are often prescribed for treating short-term acute pain. But which among them is a better choice of pain medication, and are they related are some questions that often cross the mind of people while choosing between the two. 

This guide meticulously evaluates the uses and health risks of the Musflex pill, further comparing its potential with the Soma pill. 


What Is Musflex Pill: An Overview 

Musflex pills are muscle relaxers formulated with 350mg of Carisoprodol. It is further available in two other variants-




  • Musflex compuesto (Compound)- It is formulated with 200mg of Carisoprodol and 500 mg of Naproxen. It is classified as a muscle relaxant with analgesic and anti-inflammatory properties [2]. 

  • Musflex Plus is prescribed for moderate pain and has muscle-relaxing and analgesic properties. 


Know the active compounds of Musflex :

Carisoprodol - The FDA approves Carisoprodol for treating the pain associated with acute musculoskeletal conditions. When taken as an adjunct therapy in combination with rest and physical therapy, it works faster and shows better results. Once metabolized, it rapidly converts to Meprobamate, which also aids as an analgesic and is classified as a Schedule IV drug in the united states.


Naproxen - It is present only in the Musflex compound. Naproxen is a non-steroidal anti-inflammatory drug (NSAID) often prescribed for treating the pain associated with rheumatoid arthritis, menstrual cramps, fever, and gout. The medical use of the analgesic was approved by the FDA in 2016 and is connected to its mechanism of action as an anti-inflammatory compound.

Note- Non-steroidal anti-inflammatory drugs (NSAIDs) are a therapeutic drug class that reduces pain, decreases inflammation and fever, and prevents blood clots.

The Benefits Of Musflex Pills

These muscle relaxer is gaining popularity among users due to their high efficacy. The amalgamation of the two active compounds works against a broad spectrum of muscle and body pain.

The presence of Naproxen makes Musflex tablets a promising analgesic for treating Myositis, which results from inflammation and discomfort in the muscles. In addition, it can help manage body pain from muscle spasms, backache, sprain, arthritis, and discomfort in the joints. 


How Does Musflex Muscle Relaxer Works? 




The mechanism of action of the muscle relaxer is determined by its two active compounds. So, let us break down the individual working mechanism of these compounds. 

The Working Mechanism Of The Active Compound

Carisoprodol - It begins to work by preventing pain stimulation from the affected part of the body from reaching the brain receptor. Carisoprodol is metabolized in the liver to form Meprobamate (the primary metabolite) on reaching the body. It is readily absorbed from the gastrointestinal tract, i.e., the small intestine and stomach [4]. 

Following the absorption, Carisoprodol is distributed to the CNS. The protein binding factor of Carisoprodol is 60%, and meprobamate (metabolite) is 25% [4]. 

The metabolic process of Carisoprodol takes place in the liver and is eliminated through the assistance of the kidney. The half-life of Carisoprodol is 100 minutes, and that of meprobamate is 6 to 17 hours [4]. 

Pharmacokinetics Of Musflex Muscle Relaxant

Based on the data available on the manufacturer's official website after numerous studies and clinical trials, we can outline the following pharmacokinetic details of the Musflex pill [5].

The action and efficacy of Musflex 350 mg are similar to the Soma pill. However, it is effective for treating moderate pain. For severe muscle spasms and discomfort, taking a higher dose of Carisoprodol is advisable.
